Answer:
5 hours.
Explanation:
Given that,
Initial time, [tex]T_i=6\ pm[/tex]
Final time, [tex]T_f=11\ pm[/tex]
We need to find how much time did it take the car to arrive.
Time = final time-initial time
= 11 pm - 6 pm
= 5
So, it takes 5 hours by car to arrive.

why might genetically identical twins have different phenotype
Answer:
They may have different phenotypes because of differences in their environments, such as nutrition and healthcare. Why might genetically identical twins have different phenotypes? Any genes on the same chromosome could be linked genes, whereas only genes on sex chromosomes can be sex-linked genes.
Explanation:
Due to the effects of the environment, genetically identical twins might have different phenotype.
What is phenotype?The qualities or visible characteristics of an organism are its phenotype. It depends on how the environment and the genotype, or genetic code, of the organism interact.
Although human monozygotic twins as well as other genetically identical species may share startling physical similarities, they frequently differ in key characteristics, such as complicated diseases. The effects of the environment have generally been blamed for this variance across organisms with essentially identical chromosomal DNA sequences.
Therefore, due to the effects of the environment, genetically identical twins might have different phenotype.

Balance the chemical equation. Based on the equation, how many grams of bromine are produced by the complete reaction of 11 grams of potassium bromide?
Answer:
Explanation:
The balanced chemical equation is Cl2 + 2KBr → 2KCl + Br2. The amount of bromine is calculated as follows:
11.0 g KBr (1mol KBr/119.002g KBr * 1mol Br2/2mol KBr * 159.808g Br2/1mol Br2= 7.39 g Br2.)
What element is added to copper to make bronze? Why is this important for making bells?
Answer:
The correct answer is - tin.
Explanation:
Tin is the element that is mixed with copper to make bronze as bronze has many unique properties such as crisp sound quality and hardness. The hardness of the bronze allows them to make a good quality sound is come by adding tin to copper restricts the free flow of electrons of the copper atoms.
The pure metals have molecules present in an orderly manner and allow the electrons to free flow. This is why bell makers use bronze as it does not allow electrons to move freely which makes it hard and makes a good sound.

This law states that a still object will stay still unless a force pushes or pulls it. A moving object will stay moving unless a force pushes or pulls it. Gravity and friction are forces that constantly push and pull the "stuff" on earth. So, when we roll a ball, it slowly comes to a stop.

F = 2 atoms
Further explanationGiven
Skeleton equation(unbalanced equation) :
NaCl+F2⇒NaF+Cl2
Required
The number of atoms
Solution
We balance the reactions to find the reaction coefficient, which is then used to calculate the number of atoms in the reactants and products
Balanced equation
2NaCl + F2 → 2NaF + Cl2
A balanced reaction will show that the number of atoms in the reactants and products is the same
Reactants :Na = 2 atoms
Cl = 2atoms
F = 2 atoms
Products :Na = 2 atoms
F = 2 atoms
Cl = 2 atoms

Why was Wegener’s theory of continental drift almost completely discarded?
A. It didn’t explain how continents fit together.
B. It didn’t explain how mountains formed.
C. It wasn’t supported by fossil evidence.
D. It didn’t have a mechanism for how drift occurred.
Which of the following is evidence that the continents were once part of a supercontinent called Pangaea?
A. Island Arcs
B. Deep ocean trenches
C. Glacier scrapings
D. Mid-ocean ridges
Answer:
1: The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his hypothesis was rejected by many for lack of any motive mechanism. 2: The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.
Answer:
1. D
2. C
Explanation:
1. Although now accepted, the theory of continental drift was rejected for many years, with evidence in its favor considered insufficient. One problem was that a plausible driving force was missing. A second problem was that Wegener's estimate of the speed of continental motion, 250 cm/year, was implausibly high.
2.The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.
If 1.2 g of ammonium bicarbonate is treated with .75 grams of sodium chloride, 63.0075 grams sodium bicarbonate will be produced. In this reaction NaCI is limiting reagent. True or false
Answer:
True
Explanation:
Limiting reagent is the reactant that determines the progress of the reaction. It determines how much of the product is formed.
The equation for this reaction is;
NaCl (aq) + NH4HCO3 (aq) → NaHCO3 (aq) + NH4Cl (aq)
From the reaction, 1 mol of NaCl reacts with 1 mol of NH4HCO3 to produce 1 mol of NaHCO3
Converting to masses using; Mass = Number of moles * Molar mass
58.44g of NaCl reacts with 79.056g of NH4HCO3
If we were to sue the whole 1.2 g of NH4HCO3 we would require xg of NaCl
58.44 = 79.056
x = 1.2
x = 0.887g
The fact that 1.2g of NH4HCO3 requires 0.887g of NaCl (which is less than the available 0.75g) means that NaCl is the limiting reagent.
